Specification of Letters Patent. Application flied December 1e, 1905.

Patented Aug. a, 1909. serial No. 293,083.

To all who-m it may concern."

Be it knoivn that I. Jaton STKE-BEN, residing in Kalamazoo. in the county of Kala ming-ooignnltate of lvlieh' xImproved Globe-l alve, of which the t'ol oivingmis a specilicationl This inv-'eition` which relates to improvements in globe or cheek valves, andmore particularl)v refers to thatA tvpe of valves l disclosed in inv Patent l\o. 783,597 dated Feb. ZS, 1905. has for object to provide a valve of the type stated. in which the several parts are especiall7 designed for effect# ing economiv in the mannfactnre'of the valve l5- and whereby the severalv parts. When assenr.

95 drawings. in Which:--

Figure l. is a vertical section of'myv improved construetion'of valve, the same being closed. lower portion thereof, the valve head being shot-vn litt-ed fromthe seat by the steam pressure Vagainst the under side thereof. Fig. B. is an enlarged detail ot' a vertical section of th zontal section on the line 4-4 of Fig. 3. Fig. 3. is a perspective view of the'tu'bular valve standard. parts being broken away to show the location ot' the packing and'its retainer Fig. o, is a detail perspective view ot the valve head. i

ln its practical construction. mv improved valve includes a T-shaped casing A having the usual oppositel;7 disposed inlet and out let openings A and A2, and the central tubular extension A3 midwax7 the inlet and Ioutlet ends, the said extension and inletV and outlet` ends being internally threaded, as shoivn. At the inlet side. t ie casing A has a pendent Wall Bthat has ln inwardly projectedl flange Z) and the said wall is of semieircular shape and' merges with a similar iv'all G that extends fupwardlv from the casing bottom at the outlet end and which i5 has a flange 0,' the flange members c and o formingfthe annular valve seat'. By reason Fig. Q. is a similar1 lview of the packing gland for the valve U stem. lits normal or uncompressed form being 35 indicated in dotted lines. Fig. 4. is a horisubstantiallv spherical of -forming the vvalls, andB as shown,

under the ivall B and thence over the wall. C tothe outlet as clearly` indicated by arrows on 191g'. '2. I

the flou' of steam into theinletendlwill be Cooperating With the valve seat cis al valve i) that oniprises'a head having a concaved under t'aee l and an annular seat I)2 surrounded .b v the pendent fannular flange d". the said 'llange d: when the valve is down andl on the valve seat surrounds thetlange fi-f and aids in holding the valve head in 'true position. rlhe valve l) also includes a stem D t'or slidablv engaging a socket'e'in the` loiveJ' or head end of the plunger F. the said head j' heilig extcrnalh7 threaded as at f2 for reasons to be explained. lt vvill be noticed that the'inner .-'iange ffl-"is beveled'on the' same angle that the scattare (--71 ot' the'members B and C are beveled. such correl-atiw.x arrangement o-t' parts providing t'or a true yrestii-ig orjcoiltacting of the valve head on the valv seat when at its closed position.

I E designates the plug member ot the valve casing. the loiver endy ot 'which terminates in an -extension e 'e2 tor engaging the -internal threadsot` the part of' the ca.- ing. and it also has internal threads e toreceive the threaded part f2 otl the head ot' the plunger I*` and-the said plug has a socket et for the reception ot the upper end of the head fivhen it is'manuallv raised b v tl'irning the valve handle f4. v.\t

the upper end the plug E is tormedavith a shaped .socket e to or bearing face-ot' the externall)7 threaded :is at:v

receive a flexible bushing for the stem of the alve adjuster l? very thin metal sleeve 71 mounted within the bore 7i of a rubber ball H. ln practice. the sleeve and ball are fitted upon the stem F het'ore the handle ft is attached thereto and the said hall ll is compressed and caused4 to tightl)- bind inthe socket, e by a screw cap E that enters the threaded end of the socket and which in turn is locked from working loose b v a set screw E2 that takes through the side ot the'plug E. as is clearly shown in Fig. 1. B v providing the sleeve within `the rubber ball llprevents the stem F from sticking dm'ing the adjustment of` the valve and at the same time the ball H effects the desired packing about the stem andwvithout making a too tight joint.
